23 Maxim's multi-channel, wide-bandwidth TIAs deliver the highest bandwidth in the industry, low noise, and low power consumption in a small package. They also offer the following capabilities: • Amplify input pulses in nanoseconds to achieve greater resolution. Compared with the current solutions on the market, this translates into 2 times higher bandwidth and 20 percent less power consumption overall. • Support bandwidths of 160 MHz and 490 MHz. Operating at 490 MHz, the TIAs consume only 181.5 mW of power. • Support 128 channels. By packing more channels in one IC, LiDAR systems gain valuable space while reducing power consumption significantly. Highly integrated ICs also reduce the bill of materials. • Enable highly accurate distance measurements equally well for distant and nearby objects through low-noise operation—2.1 pA/ √ Hz input-referred noise density— resulting in high signal-to-noise ratios. • The TDFN package size of 9 mm 2 provides the industry's smallest overall solution. • The selectable gain feature potentially eliminates the need for additional amplification by using two pin-selectable transimpedance values of 25 kΩ and 50 kΩ. • Built-in power protection capable of withstanding input currents up to 2 A (10 ns) and fast overload current recovery time of only 2 ns (up to 100 mA). A low-power mode of 26 mW is available when not in use. "With [receiver- end] hardware also becoming denser, electromechanical and optics engineers can push the bounds on LiDAR package sizes and form factors, allowing us to move aesthetically from an unsightly lump to a more subtle sensor."
